茶多酚锌盐热分解法制取氧化锌纳米微粉

Preparation of Nanometer ZnO by Thermal Decomposition of Zinc Salt of Tea Polyphenols

由于从茶叶中提取的多羟基酚性物质茶多酚具有活性羟基多、无毒无害、对金属离子沉淀率高的优点 ,因此利用茶多酚作为有机沉淀剂制备了氧化锌纳米微粉 ,研究了前驱体的形成条件、分解温度、焙烧时间 。

Tea polyphenols extracted from green tea has much hydroxy but no toxicity,and more sedimentation ratio of metallic ion.Using tea polyphenols as precipitator,ZnO nanometer particles were prepared.The formation condition of precursor,the temperature of thermal decomposition,the time of heat treatment had been studied.
